These firewalls had been created with regard to response to the evolving application sophistication as well as malware. Malware developers and developers for applications have outwitted majorly the long ports depending upon the traffic classification through developing techniques for port evasion into the programs. Malware today piggybacks such applications for entering the networks and has become networked increasingly. These firewalls have acted as a platform for enforcing policy on network security and inspecting network traffic. These next generation firewall systems are determined through several attributes. One attribute is first generation firewall standard capabilities (Kaur and Rao 77). This is inclusive of filtering the packet, inspecting the protocol of state-full nature, translation of network address and connectivity of VPN.
Second attribute is true integration of preventing intrusion. This is inclusive of the support for facing vulnerability and signatures facing threat. It includes rules based suggestions depending upon the activity of IPS. The total of such collaboration of functions through the next generation firewalls is higher than the parts of individual nature.
Third attribute is complete visibility stack as well as identification of application. This has the ability of enforcing policy at the layer of application in an independent nature from protocols and ports.
Another attribute is the intelligence of extra-firewall. It has the ability of taking data from externalized sources and making decisions of improved nature (Kaur and Singh 200-204). Examples are inclusive of blacklists being created and have the ability of mapping traffic to the customers and groups through use of active basis of directories.
Another attribute is modern threat landscape adaptability. It has the ability of supporting up gradation based paths for integrating newer feeds of data as well as techniques for addressing threats in the future. In-line support is a crucial attribute offering minimum degradation of performance or network operations disruptions.
